The planning for Overlord, like most large military operations, required many different tasks to be coordinated. This required that precise timelines be ready for distribution to thousands of people. Unfortunately, the precise date for the launch was anything but precise; there were many 'fudge factors', of which the weather was one of the biggest.
The solution was to start the program on Day D at Hour H.
One order might be 'embark 4th Infantry D+3'.
Another might be 'emplane 82nd Airborne H-6'.
Commanders everywhere would wait for the signal that gave the date of D Day and the time of H Hour. They could then quickly put the actual date-times onto their orders.
It turned out that, when the planning finally came together, D-Day was about 30 hours long. Many in the planning staff began referring to it as 'the longest day in history' and "the longest day" did get used as a nick-name.
Note. the system of day d and hour h was not invented for the occasion - soldiers have been using it for a long time. The two orders above were invented for this answer and should not be taken as historically correct.
THe answer is the longest Day
D-Day was June 6, 1944 - the Allied invasion of German-occupied France in Normandy. The code word for D-Day was Mickey Mouse.(Note: D-Day is simply a codeword, like H-Hour.)
D-Day was designed to be the last push on germany. D Day was the first step in taking the war back to Hitlers Europe. At that time the Russians were pressing in the East and were taking most of the casualties in the war. Italy had been invaded by the Allies but a new front was required. Dday was the day on which (at that time) the greatest sea armada ever known was lauched against the Normandy coast. The invasion area was set into five beaches. Despite what Hollywood says it was not a solely US affair. The Americans had two of the areas, the British had two and the Canadians had one.
They landed on Normandy beach.. and were pressing inwards into Europe to take down the Nazi regime
It was called a splendid little war.
Pearl Harbor was not an invasion, it was a bombing.
It was the beginning of the Allied invasion of Europe. It began with the landing at Normandy, France. The invasion saw the largest amphibious assault in history
D-Day was the Allied invasion of German occupied France, on the beaches of Normandy on 6 june,1944.
Yes, they did not anticipate where the invasion would take place, not enough land was covered by their troops. They also thought that Dday would be postponed due to weather.
D-Day
Operation Overlord .
The code name for this invasion was Operation Barbarossa.
For Skirmish Dday you have to call. I assume it is the same for Oklahoma and other big dday games also.
